Just insane what's going on here. Johnson was down 2-4 in the fourth set tiebreaker and looked like he was dead. At 4-5, he breaks off a ridiculous forehand drop shot winner from the baseline. Guns a forehand at 5-6 to fight off a second match point. Pops an ace to close out the set. This kid is straight balls.

I think he will get destroyed in the fifth, but what you have to understand is he had an absolutely insane gauntlet to qualify. Johnson won 17-15 in the third set in the first round of qualification, then two more rounds just to get in the main draw.
